seismostats.analysis.estimate_mc_maxc(magnitudes: ndarray, delta_m: float, correction_factor: float = 0.2) → float#

Returns the completeness magnitude (mc) estimate using the maximum curvature method.

Parameters:

  • magnitudes – Array of magnitudes to test.

  • delta_m – Bin size of discretized magnitudes. Sample has to be rounded to bins beforehand.

  • correction_factor – Correction factor for the maximum curvature method (default value after Woessner & Wiemer 2005).

Returns:

mc – Estimated completeness magnitude.
